2006 Chevrolet Avalanche LS 1500 4dr Crew Cab 4WD SB (5.3L 8cyl 4A)
I run my truck pretty hard high speed and for long periods and over the years I have averaged over 17 mpg highway and city combined, I have even pulled small trailers and the gas mileage was still good, I'm going to purchase another Avalanche soon this will make my third one and am very satisfied with the overall performance.
